WILLIAM P. PITT, OF KANSAS: CITY, MISSOURI, ASSIGNOR TO IRVING-PITT MANU- EACTURING COMPANY, OF KANSAS CITY, MISSOURI, A CORFQRATION OF MISSOURI.

TEMPORARY BINDER.

To all whom it may concern:

Be it known that I, TVILLIAM P. PITT, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Temporary Binders, of which the following is a specification.

My invention relates to improvements in temporary binders. It is particularly adapted for use in connection with binders of the type having posts telescopically fitted and attached to two leaf embracing members.

One of the objects of my invention is to provide a binder of the kind describet, which is cheap to make, easy to operate, durable, not liable to get out of order, which may be cheaply bound with canvas or other binding material, which will reliably hold the leaf embracing members from moving outwardly from any position within their rangeot movement, which will present an attractive appearance and which is efiicient in operation.

A further object of my invention is to provide a novel extensible lock for connecting the post-supporting members, which will not require notching of the corners of the loose leaves, which will occupy small space and that located in the marginal portion at the outer edges of the leaves, which will hold the binding material on the post-supporting members, and which may be at tached to the post-supporting members after the binding has been applied thereto, which may be quickly and easily locked and unlocked and which has means for being reliably held in either the locked or the unlocked position.

My invention provides further a novel post-supporting member which can be cheaply bound and which eliminates expensive hand binding and which has novel means for attachment to a cover.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings,which lustrate the preferred embodiment of my invention,

Fig. 1 is a perspective view, partly broken away, of a binder provided with my improvement.

Fig. 2 is an enlarged plan View, partly broken away, with the covers in the open position Fig. 0 is an enlarged view of the binder shown partly in plan, partly in longitudinal section and partly broken away.

I Fig. d is a perspective view of the two anlgle plates shown separated from each ot ier.

.Fig. 5 is an elevation, partly broken,

cal section through one of the end locks and parts connected therewith.

Fig. 11 isa perspective view of one of the slidable members of one of the end locks.

Fig. 12 is a perspective view of the other slidable member of one of the end locks.

Similar reference characters designate similar parts in thediiierent views.

1 and 2 designate respectively two rightangled plates, each having secured to it inwardly extending posts 3, adapted to be slidably titted in tubular posts 4, attached to the other member. The flange of each plate 1 and 2, Fi 4, to which the posts are attached has one longitudinal edge formed into barrels 5, adapted to receive a pintle 6, which is mounted in the adjacent edge of an adjacent cover 7.

Each member 1 and 2 is embraced on both sides and all its edges by a sheet of binding material 8. i

The post-supporting members 1 and 2 are adapted to embrace loose leaves 9, Fig. 1, which are mounted in the usual manner on the posts 3 and 4t.

For releasably holding the leaf embracing members '1 and 2, from outward movement, from any point within their range of movement, I provide two end locks, which are extensible and which connect the members 1 and 2 adjacent their ends respectively.

The two end locks are similar in construction so that a description of one will sutlice for both. a

Each end lock comprises two members 10 and 11, the member 10 being provided on its outer side with longitudinal parallel flanges 12, respectively slidably fitted in two longitudinal channels 13, provided on the inner side of the outer member 11. One end of the member 10 is provided with a channel portion 1 1, which embraces the adjacent end and the inner and outer side of the post supporting member 1, see Figs. 1, and 5 to 12.

One end of the member 11 is provided with a channel portion 15, which embraces the adjacent end and the inner and outer sides of the flange of the member 2, which supports the posts 3 and 4.

The channel portions 141 and 15 are fitted over the binding 8, after the latter has been applied to the members 1 and 2, thereby protecting the binding material and holding it in position. After the channel portions 1% and 15 have been applied to the plates 1 and 2, they may be firmly fastened thereto by punching indentations 16, Figs. 1 and 10, which indentations enter holes 1'? respectively, which are provided in each end ofeach plate 1 and 2, see Fig. 1, and Fig. 10.

Extending inwardly from each plate 11 is ahorizontal pin 18, on which is pivoted a cam 19, Figs. 5 to 8, which has a wedge shaped projection 20, adapted to engage with the adjacent flange 12, as shown in Figs. 5 to 7, at any point within the range of movement of the member 10, and in a manner such that any outward movement of the member 10, will tend to force the pro? jection-2O between the pin 18 and the flange 12, and thus'wedging the cam 19 tightly against the flange 12, thereby locking the members 10 and 11 against outward movement. The projection 20 is arranged to engage the flange .12 at the inner side of a transverse plane intersecting horizontally the pin 18. By means of this construction, the cam 19 permits the members 10 and 11 to be forced inwardly but holds them from moving outwardly from any point, when,

the cam 19 is in the locking in Figs. 5 to 7.

For manually swinging the cam 19 to and from the locking position, it is provided with a finger hold 21, which extends outwardly through a slot 22, in the plate 11.

Preferably the cams 19 are, for convenience in manipulating, both arranged on the members 11, so as to be swung in the same directioirto the locking position, that is, toward the covers 7. To release the cam 19, the finger holds 21 are both swung away from the covers 7, to the position shown in Fig. 8, in which position the projections 20 will be respectively released from engagement with the adjacent flanges 12.

Forreliably holding the cam 19 in either the locked position shown in Fig. 7 or in the unlocked position shown in Fig. 8, there is provideda spring 23, one end offwhich position shown is attached to the plate 11, and the other end of which is attached to the adjacent cam 19, the arrangement being such that the pressure of the spring 23 will be toward the pin 18, and such that when the cam 19 is moved from the unlocked position shown in Fig. 8 to the locked position shown in Fig. 7 or in the reverse direction, the end of thespring which is attached to the cam will cross a straight line connecting the centerof the pin 18 with the point on the plate 11, at which the spring is attached to the plate 11.- By means of this construction, the spring 28 is double-acting and will releasably hold the cam 19 in either the locked or the unlocked position.

One of the flanges 12 of the member 10 is provided at its inner end with a projection 24, Fig. 11, which projection, after the parts have been assembled, as shown in Figs. 5 to'9, is bent to the right, as shown in Figs. 7 and 8, so as to engage the projection 20 of the cam 19, when the latter is in either the locked or the unlocked position. If the member 10 is drawn outwardly, a sufficient distance, the projection-2 1 will engage the projection 20 of the adjacent cam 19 and will swing the latter to the locked position, shown in Fig. 7, thus preventing the members 10 from being accidentally withdrawn from the members 11. This will occur at a point in which the telescoping posts 3 and 4. will still be engaged with each other. The binder will thus be held by the cams 19 from being opened to a position in which leaves can become accidentally detached from the posts 3 and 4:.

In the construction of the binder and the assembling of the parts thereof, the strips of binding material are folded over and glued to the sides and all of the edges of the angle plates 1 and 2, which is a simple operation and which eliminates expensive hand manipulation. The posts 3 are then slipped into the posts 4, after which the channel portions 1% and 15 of the members 10 and 11 are respectively forced onto the adjacent ends of the angle plates 1 and 2 and over the binding material 8 thereon. A punch is then used to force indentations 1.6 into the holes 17 from the channel portions -14I and 15, thus securely holding the plates 10 and 11 rigidly fastened to the members 1 and 2, without any other attaching means. The pintles 6 are then engaged with the barrels 5 and covers 7, thereby'completing the assembling of the binder.

In the operation of the hinder, the finger holds 21 are both swung from the locking position shown in Figs. 5 to 7, to theunlocked position shown in Fig. 8, after which the members 10 and 11 are pulled outwardly to the open position, after which the leaves 9 *having the usual edge slits, slipped onto the posts at and 3.

not shown are 1 The finger holds 21 are then swung toward the covers 7 to the looking position shown in Figs. 5 to 7 after which the memberslO and 11 are forced toward each other until the leaves 9 are clamped together by the members 1 and 2. The locking cams 19 will hold the members 1 and 2 in the clamping position, from which position the members 1 and 2 may be released by first swinging the finger holds 21 to the release position and then drawing the members 10 and 11 outwardly.

It will be noted that between the side edges of the leaves 9 and the side edges of the covers '7 and the end edges of the memhers 1 andQ, there are clear marginal portions 25, Figs. 1 and2, such as are usually,

provided between the edges of the leaves and the covers of a book, and that the locks are located wholly within these marginal portions respectively, thus eliminating the necessity of notching the corners of the loose leaves 9.

I do not limit myinvention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from thespirit of my invention.
